The answer is D. If you aren't consistent with your drop positions, then your data may be invalid. To be frank: it basically screws over the experiment.
Answer:
A is true
Explanation:
Other all are wrong I guess
Answer:
Maximum height, h = 1.74 meters
Explanation:
It is given that,
A potato is shot out of the cylinder. It is a case of projectile motion. The potato makes an angle of 17 degrees above the horizontal.
Initial speed with which the potato is shot out, u = 20 m/s
We have to find the maximum height of the potato. The maximum height of a projectile (h) is given by the following formula as :

Where
= angle between the projectile and the surface
g = acceleration due to gravity

h = 1.74 m
or h = 1.74 meters
Hence, this is the required solution.
Electrostatic forces are non-contact forces; they pull or push on objects without touching them
Answer A sounds about right
